DRAWING TAP FOR AERATED OR CARBONATED WATER.

SPECIFICATION forming part of Letters Patent No. 664,375, dated December25, 1900.

Application filed July 2, 1900.

To all whom it may concern:

Be it kn own that I, BERNHARD BARON ,a citizen of the United States,residing at London, England, have invented a certain new and usefulImprovement in Drawing- Taps for Aerated or Carbonated Water, of whichthe following is a specification.

My invention relates to improvements in drawing-taps for aerated orcarbonated waters and the like. i

For drawing off aerated waters, particularly where such are made on alarge scale, as by machines which aerate or carbonate water drawndirectly from the main .or an intermediate vessel by bringing it intocontact with the gas, so that it may be taken oif at once forconsumption, it is desirable to use a draw ing-tap in which the liquidis allowed to first enter a chamber, after which a snifting-valve isopened to let off the gas from the top of such water, and finallyanoutlet-tap is opened to allow the water to How out into the glass orreceptacle, which it does quietly and without having its contained gasknocked out of it by its rapid rush into the receptacle. My inventionrelates to this kind of drawing-tap, its objects being to simplify theconstruction of the parts, to render the outlet-valve automaticallyclosing by the pressure of the liquid and gas in the chamber, and toprovide a mixing jet or device which is useful when the aerated water isdrawn ordischarged into a glass or receptacle in which has been placedsyrup or other flavoring or medicated matter, by which means a veryeffective mixing is obtained without the use of a spoon or other means.

My invention is illustrated in the accompanying drawings, in which-Figure 1 is a sectional elevation of the apparatus looking from thefront. Fig. 2 is a sectional elevation taken at right angles to Fig. 1.Fig. 3 is a sectional plan on line A A, Fig. 1. Fig. 4 is a sectionalplan on line B B, Fig. 1; and Figs. 5, 6, and 7 are diagrammatic viewsabout on the line C 0, Fig. 1, to show different positions of theinlet-valve.

The apparatus consists of a cylinder 1, preferably of glass, held inupper and lower metal caps 2 3 by means of screwed rods 4, which areprovided with nuts by which this upper cap may be removed. The lower capcarries the outlet-valve, which according to my present inventionconsists of a flap 5, 01 metal eri'al No. 22,321. tNo model.)

and preferably ofsonie little weight,provided with a rubber or othersuitable facing 6, which may be atfixed to it by ascrew and washer 9,such flap being adapted to cover a passage 7 in an extension 3 of thelower cap. The valve 5 is loosely hinged to the cap 3 by means of twocurved pins 10 10, secured at their lower ends in the cap, each pinpassing somewhat loosely through a hole in the flap, so that by lifting(when the lower cap is removed) the flap and turning it back-it can beentirely removed from the free ends of the pins 10, thus rendering itconvenient to clean the valve, the chamber or the passage 7, and alsoproviding a freely-working valve. Such valve carries a more or lessvertical rod 12, the length of which is such that it will reach up toand abut against the edge ofa horizontal cam 13, carried by a tubularextension 14 of the inletvalve plug 15. This plug 15 seats in a recessin a head 16, through which the extension 14 also passes. The head 16 isscrewed to the upper cap 2 at 17. The plug is provided with a reducedpart 18 and a stem 19, which are surrounded and held in the head 16 by acollar 20, screwed into such head and secured by a locking-nut 21. Thestem 19 is provided with a handle 22. The head 16 is provided with apipe 23, connecting a passage 24 therein with the interior of a pillar25, which carries a pipe 26 for a liquid-supply nnder pressure. Suchpipe 26 communicates with another passage 27 in the head 16, and thehead also has a further passage 28, communicating with a pipe 29, whichpasses down to the lower cap 3, enters the dischargepassage 7 in theextension 8 of same, and terminatesin anozzle 30. The passage 24 whereit opens into the recess in head 16 is enlarged or lengthened, as shownat 37, Fig. 3, for a purpose hereinafter explained. The pipe 29 isadapted to be disconnected, so that it may be removed when the chamberis to be taken to pieces, and I eiiect this by means of a nut 31,surrounding such pipe and abutting against a head 32 of same to hold itin a re cess of the head 16 when the nut is screwed into same.

The plug 15 contains a passage 33, one end of which forms part of thepassage in the tubular extension 14,while the other is so formed that itopens onto the lower face of the plug 15. Said plug also carries afurther smaller passage 34, which is so formed that each end I in Figs.1 and 5, the passage 33 connects the liquid-passage 27, through thetubular extenv sion 14, with the interior of the chamber 1, theoutlet-valve 5 being closed by the pressure of-waterand gas, as its red.12 lies then against the non-operative edge of the cam 13. A movement ofthe handle then brings the passage 33 into the position shown in Fig. 6,

where it connects with the passage 24:, so that e the gas-pressure onthe top of the water in the chamber 1 is relieved through the tubularextension 14, passage 33', passage 24, and pipe 23 and snifted ordischarged into the pillar 25 or otherwise discharged into the air. v Acontinued onward movement of the handle bringsthe operativeedge of thecam 13 against the: rod 12, thus tilting same and raising theoutlet-valve 5, so that the liquid in the chamber is discharged quietlyin'to'the receptacle. The enlargement or slot. 37 of the passage 24allows the s'nifting to take place duringthe continued forward movementof the handle, so that time is allowed for it to be efie'ctu'al', andthere is no fear with a rapid movement ofthehand'le of its being out 01ftoo quickly. A further onward movement of' the handle to the oppositeposition to that shown in Fig. 1 brings the outlet-valve into theposition shown in Fig. 7, where the small passage 34 is placed incommunication with the aeratedwater passage27 and the passage 28' andpipe 29, so tha-ta small but powerful jet of water underfull pressureisdischarged through the nozzle 30 into the receptacle, thusthoroughlymixing or stirring the contents 05 same. A return movement of the:handle allows. the outlet-valve to fall: bacl; by its own weight intoits closed position. It will be seen that such valve closes by itsweight and is held closed by thegas pressure and'is opened positively bythe simple mechanism described;

butI do not confine my invention to the'particu'lar means by which suchopening. is effected-,nor do I confine my invention to the particulararrangement of passageswhereby themixing is obtained, as such jet maybeotherwise obtained from the main supply during the operation ofthehandleof the drawing ta'p';
